Kcalculating The Scalar Product Of A Vector; Kcalculating The Inner Product Of Two Vectors - Casio fx-570MS User Manual

• Example: To add Vector A = (1 –2 3) to Vector B = (4 5
–6). (Result: (5 3 –3) )
(3-dimensional Vector A)
(Element input)
(3-dimensional Vector B)
(Element input)
(VctA + VctB)
• An error occurs in the above procedure if you specify
vectors of different dimensions.
k Calculating the Scalar Product of
a Vector
Use the procedure shown below to obtain the scalar
product (fixed multiple) of a vector.
• Example: To multiply Vector C = (–7.8 9) by 5.
(Result: (–39 45) )
(2-dimensional Vector C)
(Element input)
(5 VctC)
k Calculating the Inner Product of
Two Vectors
Use the procedure described below to obtain the inner
product ( ) for two vectors.
• Example: To calculate the inner product of Vector A and
Vector B
(VctA VctB)
• An error occurs in the above procedure if you specify
vectors of different dimensions.
